Retailers' Descriptions

Here's what other sites are saying:

DMM Carabiners Ultra O Locking Carabiner-Gunmetal-Screw Lock A322. Perhaps multi day ascents sac hauling portaledges and extreme dehydration (eek) are not your bag but that doesn't mean you should turn your back on the oval biner design: far from it. At some point all of us will need to use a pulley system most likely in a rescue situation. Oval biners are important because they allow pulleys to sit in a correctly loaded and equalized position. The symmetrical shape also stops them shifting under load and potentially dislodging a marginal gear placement. The locking gate adds a final element of security to the system.

Any climber can benefit from the DMM Ultra OVAL Anti-Vibe Carabiner even if it was designed specifically for aid climbing and pulleys. Its Anti-vibe screwgate locking system offers the security you need to belay in any scenario, the classic oval shape makes it excellent for racking nuts for trad climbs, and the I-Beam construction brings the strength without the weight to stand up to any style of climbing you want. A generous rope radius will help you belay with a fat rope easier than most biners.
